Results of final focus test beam

International audienceThe beam experiments of Final Focus Test Beam (FFTB) started in September 1993 at SLAC, and have produced a 1.7 μm×75 nm spot of 46 GeV electron beam. A number of new techniques involving two nanometer spot-size monitors have been developed. Several beam diagnostic/tuning schemes are applied to achieve and maintain the small spot. This experiment opens the way toward the nanometer world for future linear collider

In connection with the international FFTB project (Final Focus Test Beam), in this work a precision device for the positioning of beam conduction magnets (''magnet movers'') developed by the Max-Planck-Institut fuer Physik was subjected to an experimental investigation. Test procedures have been developed in order to characterize positioning exactness as well as test result reproducibility. All tested 32 magnet movers meet the required positioning exactness of #<=# 1 #mu#m.

Focusing of submicron beams for TeV-Scale e+e−e^+ e^- linear colliders

First experimental results from the final focus test beam (FFTB) are reported. The vertical dimension of a 47-GeV electron beam from the SLAC linac has been reduced at the focal point of the FFTB by a demagnification of 320 to a beam height of approximately 70 nm
